Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple members with body contact points are used to detect exercise motions, then motion detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple body contact points (hands and feet) onto a single load surface, merging multiple detection functions into one integrated platform. This allows the system to detect exercises like push-ups and squats using a unified load measurement approach rather than separate sensors at each contact point, thereby reducing mechanical complexity while maintaining detection accuracy
Solution Approach 2:
The load surface serves multiple functions simultaneously: it supports various body positions (hands during push-ups, feet during squats), measures different types of exercises, and accommodates diverse user body weights. This multi-functional design eliminates the need for specialized sensors for each exercise type, simplifying the overall device structure
2Difficulty of detecting and measuring
If multiple body contact points are required for exercise detection, then motion detection capability is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically detects and measures exercise motions without requiring users to manually position themselves at specific contact points or activate sensors. Users simply perform natural exercises on the load surface, and the system self-adjusts to detect the motion through load changes, making operation intuitive and easy
3Device complexity
If a single load surface is used for exercise detection, then device complexity is reduced, but measurement precision may deteriorate
Solution Approach 1:
The patent replaces complex mechanical sensor systems with an electronic load measurement system. A single load surface equipped with load cells electronically measures force changes, substituting for multiple mechanical contact sensors. This electronic approach maintains high measurement precision while achieving mechanical simplicity
Solution Approach 2:
The system dynamically analyzes load parameters (magnitude, rate of change, duration) to distinguish between different exercise types and valid motions. By monitoring multiple parameters simultaneously from the single load surface, the system achieves accurate exercise detection without requiring multiple physical contact points

AI summary
An exercise detection apparatus including: a load stage comprising a load surface onto which a load of parts or all of a human subject is applied; a load measurer for repeatedly or continuously measuring the load on the load surface; a calculator for calculating a difference between adjacent local maximum and minimum in the load varying over time measured by the load measurer repeatedly or continuously; and a detector for detecting a motion of the human subject when the difference calculated by the calculator is within a range.
